编程：输入三个数x,y,z.然后按从大到小输出

Answer 1

#include <stdio.h>
float max(float a,float b);
void main()
{
float x,y,z,t,a,b,c,d,e,f;
scanf("%f,%f,%f",&x,&y,&z);
a=max(x,y);
b=x+y-a;
d=max(a,z);
c=a+z-d;
e=max(b,c);
f=b+c-e;
printf("%f,%f,%f",d,e,f);
}
float max(float a,float b)
{
if(a>b)return a;
else
{
float t;
t=a;
a=b;
b=t;
}
return a;
}

Answer 2

算法：
input X，y，z
dim max
compare X，y
（x>y)
max=x
(x<y)
max=y
(x=y)
max=x
compare max,z
(max>z)
max=max
(max<z)
max=z
(max=z)
max=max

print
max
